, confection filling machines.

The main object of my invention is to provide simple and easily mademolds which are of such nature and construction that it will produceclean cut confection fillings and casts, free from drips and tails orirregular projections.

Another object is to have molds of the character indicated which areeasily placed in position and as easily removed and which are also veryefficient in form so as to readily co-operate with a machine upon whichthey are installed for producing a uniform product.

Other objects, and the advantages accruing from the nature,construction, and use of my invention will appear more fully herein asthis specification proceeds.

This application is in the nature of a division of my co -pendingapplication Serial No. 734,885 filed July 13, 1934, which issued Sept.29, 1936, as Patent No. 2,055,605.

Upon confectionery machines utilizing molds of the present type, andintended for the manufacture of chocolates, confections and the like, itis usual first to pour a chocolate shell into the molds in the moldplates which are preferably moved past a chocolate pouring device, afterwhich said molds are passed beneath a cremepouring device which poursthe creme or other desired filler into the shell to form a core therein,and the shell is subsequently closed by a cover cast into positionthereon.

The main disadvantage appearing in the operation is the difiiculty ofpouring the creme prop erly, due to the tough slimy and viscouscharacter thereof, causing the pouring to be difficult and troublesome,as the creme during pouring tends to be drawn out into long toughthreads or tails which become deposited upon the upper surfaces andedges of the mold plates in such manner as to prevent the subsequentpouring or casting of the cover. The material poured also tends to dropfrom the edges of the molds and between molds onto the mold frames andcon veying chains or other parts in undesirable manner.

Hence with the foregoing objects in view and in order to eliminate thementioned disadvantages, the present invention is designed to make iteasily possible and practical to pour creme or other filler intochocolate shells and the like in such manner that the tough thread ortail formed at the end of the process is not deposited upon the uppersurface or edge of the mold plate involved. The operation of the pouringhopper for the creme which assists in bringing about this desirableresult, as well as the mechanism for operating the same are fullyexplained in my co-pending application above identified, and as thesestructures form no actual part of the present invention, it will sufficeto show the pouring hopper in position over the mold structure, togetherwith means for supporting and raising said mold structure so as to bestco-operate with the hopper and utilize the shape of the mold plate andmold structure.

The molds are hollow cups of various shapes, a greater or smaller numberof said molds being provided in the mold plates, which are supported onmold frames adapted to be pushed into position on mold-frame holdersprovided on endless chains, in such manner that the mold frames caneasily be pushed onto and again removed from the mold-frame holders.

This exchange of the mold frames is effected when chocolates of othershapes are to be cast.

It is absolutely necessary that the mold plates with the mold formedtherein should have a plane and smooth surface, and that the said moldplates should project beyond the mold frames and the mold-frame holdersand the machinery below the same, since thereby it becomes possible toscrape away from the mold plates any superfluous chocolate, and it isthus a main feature of the invention to provide a special arrangement ofthe mold plates and the parts connected thereto.

The machine to which the invention is applied may include a continuouslymoved mold conveyor supporting fixed mold-frame holders withexchangeable mold frame with mold plates containing the said molds whichare first filled with chocolate, after which the mold plates with themolds will pass a shaking table and will be turned upside down in such amanner that the surplus chocolate runs off. Then the molds will pass acooling closet in order to be cooled sufiiciently to a very lowtemperature, so that the creme received may be as hot as possiblewithout fusing the chocolate shell formed. Now the creme is poured intoposition, and then the molds pass an other vibrating table, a coolingcloset and a heating device in order to melt the top edge of thechocolate shell, before the covering layer is applied. Then the coveringlayer is applied, the surplus material is scraped away, and the moldsnow pass over a shaking table to a cooling closet, after which thefinished confections are finally shaken out from the molds.

In the practice of my invention, the supply of material for filling themolds may be for example, a hopper I provided with pumping devices 2,and a pouring valve 3, all of which are explained in detail in myco-pending application, already alluded to, including means foroperating the pouring valve and swinging or moving the hopper in desiredmanner. However, as the details, and operation of these parts form noactual part of the present invention but merely a background therefor,mere allusion thereto as already given will perhaps suffice. Thus, thepouring hopper is intended to contain the filling material to be pouredinto the molds, while the pouring valve controls the pouring in more orless obvious manner which hardly needs to be considered here.

Nevertheless, a mold assemblage 4 is located below the pouring valve andhopper so as to receive the intended filling from the same, and willpreferably rest upon a conveyor or the like indicated at 5, the moldassemblage shown being only one of a series which may be broughtsuccessively into position beneath the hopper. In general, it has beenfound desirable to raise each mold assemblage into tolerably closeproximity to the pouring valve during the pouring, and for this purpose,the machine may have a driven shaft 6 carrying a cam I controlling theposition and movements of a bell crank lever B, 9 pivoted at I andprovided with a roller I I on its arm 8 bearing against the cam. Theother arm 9 of said lever is connected by a link I2 to an arm I3 of anelevating lever I4 which is pivoted at I5 and has a member I6 disposedbeneath rails supporting the conveyor 5. When rotation of shaft 6 causesthe cam disk I to shift lever 8, 9 in a counterclockwise direction so asto lift link I2, the latter will cause a corresponding movement of leverI3, I 4 about its pivot l5 and will thereby raise the rails supportingthe conveyor, with the result that conveyor 5 is raised and will in turnraise the mold assemblage 4 toward the nozzle of the pouring valve 3.

Now in order to efficiently receive the creme or other material intendedto be dispensed by the pouring valve, the mold equipment with which themachine is provided is of special construction and character. Obviously,the size and form of cam disk I is selected to be such that the moldscan only be raised to operative position during actual deposit of thecreme so that the molds are close to the valve and will cause thestrings or tails of creme formed by the pouring to be smeared out or offfrom the molds. If, however, after the pouring a small remainder of thementioned tough string or tail of creme should remain upon the lowerportion of the valve, the same will be broken off by the lowering of themolds.

Figs. 2 to 5 illustrate the construction of the molds per se. The moldplate consists of a sheet or fiat piece of tin plate or other suitablemetal or substance I1 attached to and forming a part of a mold frame I8formed from U-shaped iron bars in such manner that the upper surface ofthis frame projects horizontally beyond the extent of the lower portionthereof, and, as shown in Fig. 4, can be readily pushed into position ona mold plate holder I9. In the mold plate I1 the individual molds 20 maybe given their proper form by stamping so as to have the shape shown inthe drawing. In other words, the molds may be formed of a single sheetof metal or other suitable material so as to constitute an integral unitin which each mold cavity 23 comprises a mold.

In view of the fact that the upper leg of the U-shaped frame isconceivably wider than the lower leg of said frame, the frame willproject beyond the portion I9 of the mold plate holder in such mannerthat the entire mold plate will present a perfectly smooth uppersurface, especially adapted to co-operate with a scraper or the like. Inorder to re-inforce the molds, supporting rails 2| and 22 are interposedbetween the frame parts I8.

In view of the foregoing description it is evident that when molds ofthe present construction present a smooth and flat top surface to adischarge Valve, while said molds are in motion past said valve, or ifthe hopper provided with said valve is moved past said molds, the toughstrings or tails of filler which may be left after the valve has beenclosed will readily be smeared and broken off and thus the contents inthe form of fillings or casts within the molds will be cleancut'and freefrom projections or strings, and the molds themselves capable of beinginverted or turned over on a flat plate for emptying said molds withoutit being necessary to observe any special precautions to avoid stringsor runs upon the edges of the molds.

Having now fully described my invention, I claim:

1. In a mold structure adapted to cooperate with a pouring valve of ahopper upon a confectionery pouring machine, there being a plurality ofmolds, the combination of a mold frame holder adapted to be conveyedpast said hopper beneath the valve thereof, a mold frame adapted to restupon said mold frame holder comprising a pair of spaced parallelJ-shaped metal members having the longer limbs uppermost and directedoutward in opposite directions, and a plurality of spaced fiat metalribs connecting said first two metal members and being disposed invertical planes with their narrow edges uppermost, there being moldsadapted to rest upon said mold frame and having a straight upper surfaceportion which extends smoothly in opposite directions over said J-shapedmetal members so as to protect the mold frame holder and mold frame fromdroppings escaping from said pouring valve.
